The "Ethernut" Ethernet starter kit is your best choice for hassle-free access to embedded Ethernet technology.

The kit features a small and inexpensive Ethernet Module that allows you to easily add 10/100BaseT network capability to your applications.

The hardware, as well as the preloaded OS and TCP/IP stack are open source and may be used within non-commercial and commercial, open- and closed-source projects without fee or royalties.

Ethernut Board Features

In a board area of only 80mm x 100mm (3.15" x 3.94") you get a complete embedded Ethernet - TCP/IP solution and a web server. The hardware design includes a small board, which is equipped with an Atmel ATmega128 CPU and a SMC LAN91C111 Ethernet Controller. Its expansion connector allows easy attachment of add-on boards such as the Medianut Add-On.

Ethernut Software

The well documented software is an Open Source implementation of a Real Time Operating System called Nut/OS and a TCP/IP protocol suite named Nut/Net.

Several application examples are provided, including an embedded Webserver, a simple RS232 to TCP/IP gateway and an Internet Radio playing MP3 streams.

Ethernut Application Development

A well documented API and more than 100 kByte free program space and 20 kByte free data memory are available to easily implement custom applications. The source code is written almost entirely in C and included on CD-ROM. The software licence allows its royalty-free use in Open- and Closed- Source Projects.

You can choose between two different development environments, the freely available GNU AVR Compiler Collection for Linux and Windows and the commercial ImageCraft AVR Compiler for Windows.

WARNING: Although this kit includes a programming adapter with both JTAG and ISP interfaces, the board's programming header supports the JTAG interface only. Plugging the ISP cable from the adapter into the Ethernut 2 board's programming header will damage the board!
